RT-1

Architecture and scope

The reference implementation combines a language-conditioned visual encoder, token compression and transformer action prediction. Its research checkpoint variants have different training contexts.

Integration and evaluation

The code release names main, multi-robot and simulation-to-real variants. A comparison should preserve those distinctions rather than assigning every reported RT-1 result to one checkpoint.

Evidence boundary

Research platform support does not establish plug-and-play compatibility with an arbitrary robot.
